Loudspeaker Test Sequences

Triggered Record Using WAV File (Version 16.0 and earlier)

May 5, 2015/在： Free Audio Electronic Sequences, Free Loudspeaker Sequences /通过： Zarina

This sequence allows you to test devices without an analog input such as tablets, cellphones and MP3 players. A stimulus WAV file is created in SoundCheck, and copied to the device under test, where it is played and the response recorded in SoundCheck as if the stimulus were played directly from SoundCheck. The stimulus WAV […]

Thiele-Small Parameters

April 30, 2015/在： Free, Free Loudspeaker Sequences /通过： Zarina

Loudspeaker system performance can be quantitatively related to a set of electro-mechanical parameters. These parameters are known in the industry as Thiele-Small parameters. They were first introduced by A.N.Thiele and Richard H.Small in a series of famous articles published in the 1971-72 Journal of AES (Audio Engineering Society). Over the years these parameters have become […]

Impedance Measurement – Dual Channel Method Using Math Post-Processing

March 11, 2015/在： Free, Free Loudspeaker Sequences /通过： Zarina

This sequence demonstrates an alternative to the traditional SoundCheck single channel impedance measurement method. A stepped sine sweep from 20 Hz to 20 kHz is played through the speaker while the signal across the loudspeaker terminals is recorded by Direct In 1 and the signal across the sense resistor (impedance box) is recorded by Direct […]

Perceptual Rub & Buzz

March 6, 2015/在： Free, Free Loudspeaker Sequences /通过： Zarina

This sequence uses the CLEAR algorithm for perceptual Rub & Buzz measurement to detect AUDIBLE Rub & Buzz. It uses a simplified auditory perceptual model to measure the loudness of Rub & Buzz distortion in phons rather than the more traditional dB SPL and % distortion units. These better identify whether distortion due to manufacturing […]

Impedance Measurement – Dual Channel Method Using Transfer Function

March 2, 2015/在： Free, Free Loudspeaker Sequences /通过： radar

This sequence demonstrates an alternative to the traditional SoundCheck single channel impedance measurement method. A pink noise stimulus (10Hz – 10kHz) is played through the speaker while the signal across the amplifier terminals is recorded by Direct In 1 and the signal across the sense resistor is recorded by Direct In 2. A transfer function […]

December 15, 2015/在： Free Headphone & Headset Sequences /通过： Zarina

IEC-60268-7: Sound System Equipment – Part 7: Headphones and Earphones is an international standard intended to characterize the performance of headphones and earphones. The standard itself is a lengthy document, 9 Sections and 3 Annexes covering 46 printed pages. These SoundCheck sequences focus on the electro-acoustic tests which are detailed in Section 8 “Characteristics to […]

Active Noise-Cancelling Headphone Battery Life Test

May 1, 2015/在： Free Headphone & Headset Sequences, Sequences – blog /通过： Zarina

This SoundCheck test sequence measures the performance characteristics of Active Noise Cancelling headphones (ANC headphones) while monitoring the DC voltage and current provided to the headphone by its batteries. The sequence first measures the passive attenuation of the headphone before moving into a loop. The loop plays a 2 minute pink noise stimulus at high […]

EN-50332-2: Measuring SPL of Portable Devices

May 1, 2015/在： For Purchase, For Purchase Audio Electronic Sequences, For Purchase Headphone & Headset Sequences /通过： Zarina

These two sequences follow the test standard detailed in EN50332-2 for measuring the maximum levels of portable music players and earphones/headphones. This section of the standard covers the individual testing of the devices rather than the combined testing that is detailed in part 1. Note that the physical setup and connections will be different between […]

Headphone Active Noise Cancellation Test Sequence

April 30, 2015/在： Free, Free Headphone & Headset Sequences, Sequences – blog /通过： Zarina

This SoundCheck test sequence measures headphone active noise cancellation (ANC). It measures both the active and passive noise cancellation and calculates total attenuation over the operating frequency range of the headphones. Passive Attenuation is the amount of noise that is reduced at the ear simply by the headphones being worn. Active Attenuation is the amount […]

Microphone Test Sequences

Measuring Digital MEMS Microphones: Frequency, Sensitivity and Power Supply Rejection (PSR) Performance

May 1, 2015/在： Free Microphone Sequences /通过： Zarina

This test suite contains 3 sequences to enable comprehensive testing of digital MEMS microphones. The first measures the frequency and sensitivity and displays two graphs: absolute level in dBFS, and the same response curve but normalized to 0 dB at 1 kHz. The second sequence uses the substitution method to test a digital MEMS microphone […]

Microphone Polar Plot Sequence

May 1, 2015/在： Free Microphone Sequences /通过： Zarina

This sequence measures the directional response of a microphone and graphs the result as a polar plot. A log sweep stimulus is played from 100 Hz to 10 kHz at each angular increment, and the acquired waveform is analyzed using the Time Selective Response algorithm. This method allows the test to be performed in a […]

Microphone Self Noise Test

May 1, 2015/在： Free Microphone Sequences /通过： Zarina

The purpose of this sequence is to measure the self noise of a condenser microphone. To do this we use the spectrum analysis step and a power sum calculation to derive an RMS rating for the unit under test. The sequence has several parts, a few of which are optional. The first section begins by […]

Telephone Test Sequences

Hearing Aid Compatibility to TIA 1083 and FCC Part 68.316

May 5, 2015/在： For Purchase Telephone Sequences /通过： Zarina

These two test sequences are designed to test the hearing aid compatibility of a telephone according to the TIA 1083 and FCC Part 68.316 standards. These sequences, which rely on the user having radial and axial HAC probes, play the appropriate test signals, measure the response and compare them to the limits in the standard. […]

TIA-920-A Sequence for Wideband Digital Phones

May 5, 2015/在： For Purchase Telephone Sequences /通过： Zarina

This sequence has been superseded by TIA 920-B test sequence. More
